PubMed, 14. Should clinical laboratories adapt to the reality of chronic kidney disease in the determination of parathyroid hormone? J Pathol Inform 2014;5:13. PubMed, 11. Several bar code readers function here. Durner J. there are three phases of the laboratory testing process that each facility should follow. Thus, the reference intervals and medical decision limits are all the same for all analyzers, Inter- and intra-assay coefficients of variations or precision check are important, No sample-to-sample or reagent-to-reagent carryover must be provided, Either in aliquoter or in analyzers, clot detection must be executed, Detection of sample integrity or hemolytic-icteric-lipemic (HIL) indices determination, Ability to handle small sample volumes; the lower the sampling volume, the better in general, Open channel are used for extra or out-of-menu tests, This means periodical/preventive maintenance, the maintenance intervals, and the duration of a maintenance or downtime. Streitberg GS, Bwititi PT, Angel L, Sikaris KA. Tietz textbook of clinical chemistry and molecular diagnostics. We know that there are a variety of workstations using different analytical techniques in a modern clinical laboratory, including reflectance photometry, electrophoresis, LC-MS/MS, as well as colorimetry/spectrophotometry, potentiometry, and immunoassay [24], which means the richer the analytical technics, the higher the number of automated analytes in clinical laboratory. In these analyzers, several detector types are used, which include different lamps: tungsten, quartz halogen, mercury, xenon, and lasers. In such event, prior to the delivery of results, customers will be informed of such circumstance and its associated consequences and give consent. Seaberg RS, Stallone RO, Statland BE. Laboratory Accreditation Board of the Spanish Society of Laboratory Medicine (SEQCML). Thus, the preanaliytical sample processing was not able to step the analytical progression, and the laboratory needed a specimen processing rate greater than what the manual handling could provide.

Postanalytical phase After the tests have been carried out, the following procedures are required to ensure proficiency in the postanalytical phase: 1. The modularity of the systems allows the customer to include, exclude, or expand any module. Other situations in which laboratory services may be interrupted include the breakdown of an analyzer system, auxiliary equipment, refrigerator, or freezer; interruption of the electricity or water supply; or other exceptional situations (for example, meteorological). The specimen caps or stoppers are removed by a device and discarded into a waste. Added to UNE-EN ISO 15189:2013 (hereinafter, the ISO 15189 Standard) requirements for the revision, reporting and release of clinical test results, described elsewhere [1], this Standard also establishes other requirements for postanalytical processes.

Management of post-analytical processes in the clinical laboratory according to ISO 15189:2012. Considerations about the management of clinical samples, ensuring quality of post-analytical processes, and laboratory information management". One can see several approaches to automated instrumentation historically. Pre- and post- analytical automation systems for specimen processing, integrated or modular, can be provided by several vendors, which was listed in 2011 by Tietz Textbook of Clinical Chemistry and Molecular Diagnostics as: Abbott Diagnostics, Aim Lab (formerly Ai Scientific), Beckman Coulter, Integrated Laboratory Automation Solutions, Labotix Automation, m-u-t America, Ortho-Clinical Diagnostics, PVT LabSystems, Roche Diagnostics, Sarstedt, Siemens Healthcare Diagnostics, Sysmex America, and Yaskawa America, Motoman Robotics Division [23]. Since the total specimen work flow in clinical laboratory accounts for about 60% of the time and effort of the total laboratory processes, the contribution of pre-analytic error to total laboratory error may be caused by the pre-analytic phase alone, which is estimated to range from 30% to 86% [31], [32], [33]. Handbook of clinical automation, robotics, and optimization. The laboratory must guarantee patient data protection by adopting all measures necessary to prevent any unauthorized access to data (i.e. This procedure can be either performed by the laboratory or by an authorized supplier upon previous agreement. Thus, it will better to summarize some distinctive characteristics of these modern analyzers as follows. Several systems can make aliquots for offline analyzers. Medical Tests in Your 20s and 30s. Clin Chem Lab Med 2017;55:34857. The future of the laboratory information systemwhat are the requirements for a powerful system for a laboratory data management? Ancak, klinik laboratuvar otomasyonu, bu ikilemi zebilir ve laboratuvar i aknda yeni dar boazlara neden olmamak kaydyla klinik laboratuvarlarda uygulanabilir. Multi control and multilevel are preferable, Water consumption as L/hour, the degree of purity, automated availability to the analyzers should be questioned, Space, temperature, and noise are important items, LIS/HIS compatibility, middleware availability, and bidirectional connection are important considerations.
